Title: Energy saving device for engine room of marine vessel
Inventor: TSUJI MASASHIGE
IPC: G05B9/02
Filed: 1985-04-12
Abstract: PURPOSE:To realize quickly an energy saving state by setting an illuminating/ air-conditioning device to a non-operating state, in case of a state that no abnormality is generated in an engine room, and resetting it to a control of an operating switch, when an abnormality is generated in the engine room. CONSTITUTION:An unmanned operating signal S2 is sent to an AND circuit 10 from an engine room unmanned operation sensor 4 by an engine room unmanned operation. On the other hand, when a selecting switch 1 is selected to a generating position of a selecting switch, an operating signal S3 of an energy saving signal generating device of a high level is sent to the circuit 10. Also, when an energy saving cancelling signal S4 is generated in an abnormality sensor 12 in an engine room, the energy saving cancelling signal -S4 is sent to the circuit 10 through a NOT circuit 17, the signals S2, S3 and -S4 are calculated by the circuit 10, a control signal S1 becomes a low level, and an energy saving switch 19 becomes on. Accordingly, use of an illuminating/air-conditioning device 20 by an operating switch 18 can be executed. However, unless the signal S4 is generated, the switch 19 becomes off, and the device 20 bcomes a non- operating state by preceding the switch 18.

IPC: B41J2/06
Filed: 1989-03-30
Abstract: PURPOSE:To obtain an ink-jet printing apparatus without the change of the printing quality wherein the ink is jetted onto a recording medium for recording, by applying an electric field in a vertical direction to the recording surface of said recording medium. CONSTITUTION:A line head 101 has the recording area not smaller than the width of a recording paper. A front electrode 102 is provided in parallel to an array of nozzles on the surface opposing a recording paper 104. A rear electrode 103 is provided as well corresponding to this front electrode at the rear side of the recording paper. In order to jet ink drops from the nozzles, piezoelectric elements may be used, or a bubble-jet method is employed. When a voltage is applied between the electrodes 102 and 103 disposed to sandwich the recording paper, an electric field vertical to the surface of the recording paper is generated. Accordingly, a pigment which is a coloring agent in the ink is restricted from moving in the other direction than the vertical direction to the surface of the recording paper, so that good printing with less feathering of the ink can be obtained.

Title: Interface controlling system
Inventor: ISHII TAKAYOSHI
IPC: G06F13/42
Filed: 1981-05-26
Abstract: PURPOSE:To realize the automatic compensation for both the interface delay time and the variance of speed of the device by transmitting and receiving the data through plural control lines by the 4-way tag line system. CONSTITUTION:An active device 1 delivers the control data to a 2-way control address data bus CAD to inform the start of an access and then delivers the control-out CTO'. An addressed passive device 2 turns on the strobe-in STI'. The device 1 detects this and turns off the CTO', and the device 2 turns off the STI' respectively. Then the device 1 turns on the strobe-out STO'. Thus the selected device 2 detects this and turns on the STI'. After this, the same sequence is repeated and executed. In this case, the timing to turn off the STI' secures a delay of the internal time required to fetch the address half. As a result, both the delay time and the variance of speed of the devices can be automatically compensated.
